Answer to Question #67013 in General Chemistry for Soo Gil Park

Question

Is it correct in the ( ) ?

1. In the system: 2NO2 = N2O4 + Q H<0; a chemical equilibrium is reached. An increase in temperature will cause a shift to the ( left ), because the reverse reaction is ( increasing ). If concentration of NO2 isincreased, the (forward ) reaction will speed up, if total pressure is decreased the volume of the system should increase, the ( reverse) reaction will be preferred.

2.Rate of reation is the change in (concentration) of a reactant or product per time unit. For a chemical reaction: nA + mB --> C + D the rate equation or rate law is given by (chemical kinetics). Main factors that affect the reaction rate are concentration and temperature. The higer the reactant's concentration, the (faster) the reaction rate. Usually, an increase in temperature is accompanied by ( an increase) in the reaction rate.

Thanks in advance.
